Not a whole lot of adjustments to make on the car if it is showroom stock. Check all fluid levels before you go. Check torque on lugnuts. When you get there, pull out all floor mats, spare tire, jack and all loose items on the trunk. At the very least I would cover the headlights and driving lights with clear tape or the like to help save from chips, breakage, etc. After the event, I would bleed the brake system and inspect the tires for abnormal wear. Check torque on lugnuts. Enjoy it!
